T @ZZ whom, t may concern:

Be it known that I, HARRISON GRANT NIDA, a citizen of the United States, residing at Delta, in thecounty of Delta and State of Colorado, have invented a new and useful Moth and Insect Trap, of which the following is a specilication.V

This invention relates to moth and insectl traps, and is designed more particularly for use upon fruit-trees in order to prevent the ravages of the ccodling-mothf? A As is Well known, fruit-growers, and more especially those whorare interested in the raising of apples, experiencegreat losses attimes from the ravages of the codling-moth, which in its larval state is known as theappley worin.l This moth lays'its eggs in theblossom end of the apples and when the eggs hatch the small worm burrows into theinterior of the apple and remains for acertain length of timerdevouring parts of the apple and growing to full size. After the worm is fully developed it emerges from the apple and descends to the ground by spinning a web, by which it lets itself down. After reaching the ground the worm immediately seeks a place to hide and undergo the change from the larval form to that of a moth. *After this change is completed the newly-hatched moth flies up into the apple-tree and deposits its eggs in the blossom ends of the apples in the manner already explained.

In order to prevent the ravages of the codling-moth, it has been the practice of orchard- Inen for years past to wrap the tree-trunks with burlap bands folded to presentthree or four layers of burlap and to form a band around the tree of about four or live inches in width. These bands are placed around the trees in' order to afford a convenient hiding? place for the worms that descend to the ground from the apples. y The object of providing a..

hiding-place for the worms in which the change from the larval or worm fornito theimoth form may be accomplished is to insure the orchardmen the opportunity to kill the worms or moths by removing the bands after the worms have hidden themselves among the folds thereof and shaking the worms or moths out upon the ground, where they may be readily and it is objectionable, because the bands have to be removed several times each season in order to insure the complete destruction of the moths. As this method depends for its effectiveness upon the vigilance of the men or boysA who remove the bands inv preventing the escape of the worms or moths shaken out of vthe folds of the bands, itis evident that all of the bands may not be destroyed.

The. prime object of. the present invention is to insure the destruction of all of the moths that develop from the'worms that hidein the bands and-also to lessen verylargely the labor incident to the destruction'of the moths.

The means employed in accomplishing the object above stated consists, essentially,` in a covering for the bands of burlap used upon that it will permit worms to crawl into the folds of the burlap bands to undergo the transformation into moths, Abut'will absolutely prevent the escape of the moths from the folds of the bands after the transformation mentioned takes place. A

forming the moth-trap is hereinafter fully deings, and has thenovel .features thereof pointed out in the appended claims.

tree-trunk Aprotected by means of a folded band of burlap and `a cover of the form contemplated yin this invention. Fig. 2 is a perspective view of the cover detached. Fig. 3 is a view in vertical section, showing the manner of applying the trap to a tree-trunk.

Referring to the drawings, in which corresponding parts are designated by similar characters of reference, Tdesignates the trunk of an appletree,around which a band of folded burlap is secured, as shown at l. The band l consists, preferably, of a piece' of burlap or other suitable textile fabric folded twice upon itself to present a suflicient number of folds. External to the band is secured a 'cover 2,which is formed, preferably, of wire-netting of the character ordinarily used in making .the trees, the covering being of such character scribed, illustrated in the accompanying draw-y destroyed. This method of checkingvthe ravages ofthe moths is only partially effective,

the moths which are developed in the folds of The preferred form of cover employed in In the drawings, Figure l is a view of a Window-screens. rI`his netting is formed with meshes between one-sixteenth and one-eighth of an inch square and is ordinarily made of iron wire protected by a coating of enamel paint. The cover 2 is formed by taking a strip of netting of suitable widthsay six or eight inches-and crimping it at the margins, as shown at 3, by passing it between suitable crimping-rollers. The strip of netting is also preferably ared outward at the edges, as shown at 4, simultaneously with the crimping operation, so that the edges of the strip of netting may not interfere with the passage of the apple-worms under the netting in their search for a suitable hiding-place in which to accomplish the transformation into the moth form. After passing through the crimpingmachine a strip of netting forming a cover 2 will be barrel-shaped, as shown in Fig. Q, and will be ready to be placed upon the appletree as a cover for one of the burlap bands. The covers 2 will be made of different sizes to adapt them for use on trees of different diameters; but it is not essential that the size of the cover correspond exactly to the diameter of the tree if the cover be sufliciently large, as the ends may be overlapped to any extent necessary to make the cover lit closely around the burlap band.

In applying the covers to the bands itis essential that the covers be fitted closely at the edges, so that no passages between the covers and the tree-trunk may be left which will be of suflicient size to permit the escape of moths from the covers. Such close fitting of the covers around the tree trunks will not, however, prevent the entrance of worms into the folds of the bands, as the crimps formed at the margins of the bands will afford passages suiiciently large for the worms.

Each burlap band l, with the cover 2 placed over it, forms a highly-effective trap for the capture of codling-moths, and the bands with the covers thereover are superior to the bands alone, in that no necessity remains for the frequent removal of the bands and destruction of the worms or moths in the folds thereof. Instead of removing the bands several times in the course of a season, as the custom now is, it will be unnecessary to remove the bands and covers till the end of the season. The Worms that crawl under the covers and are transformed into moths in the folds of the burlap bands cannot then escape, as the wings of the moth prevent it from passing through the narrow passages formed by the crimps at the margins of the covers. The moths so imprisoned under the covers over the burlap bands are of course unable to escape and injure the apples on the trees. As the moths cannot obtain their natural food, they soon die, and the necessity of removing the bands and killing the moths from time to time is entirely obviated.

While the material which I prefer to use in making covers for the burlap bands around the tree-trunk is the wire-netting above described, and illustrated in the accompanying drawings, it is to be understood that other material may be employed inlieu of thc wirenetting, and I do not desire to limit myself to the use of that material alone.

Havingthus described the nature and use of my invention, what I claim as new, and desire to secure by Letters Patent, is

l. Ina moth-trap, a tree-trunh-encircling member consisting of a strip of wire-netti ng having its marginal portions crilnped to aiiord narrow passages adjacent to the tree-trunk when the tree-trunl-encircling member is in position, said narrow passages being of such dimensions as to permit the passage of moth larv but being too small to permit the pas sage of moths after transformation from the larval state,

2. A moth-trap comprisinga treetrunh-cn circling band of textile fabric and a cover therefor consisting of a member extending above and below the fabric band and litted closely around the trce-t1unk,said cover member being provided at its margins with narrow passages through which moth larvae will pass but which will not permit the escape of fully-fori'ned moths.

3. A moth-trap comprisinga tree-trunk-encircling band of textile fabric and a cover therefor consisting of a member extending above and below the fabric band and fitting closely around the tree-trunk near the margins, said cover being provided at the points where it contacts with the tree-trunk with narrow passages through which moth larvae may pass and having the edges iiared outward from the tree-trunk to avoid interference with the passage of said larvae through the passages provided for them.

In testimony that I claim the foregoing as myown I have hereto ai'lixed my signature in the presence of two witnesses.

HARRISON GRANT NIDA.
